Hi to all
python now has grown to a versatile language that can
accomplish tasks for many different purposes. However,
AFAIK, little is known about its ability of kernel coding.
So I am wondering if python can do some kernel coding that
used to be the private garden of C/C++. For example, can python
intercept the input of keyboard on a system level? someone told me
it's a kernel thing, isn't it?
http://wiki.python.org/moin/elmer
well, straightly speaking, how can I know a key is pressed on a system-
level if
using python?
What has that todo with kernel programming? You can use e.g. pygame
to get keystrokes. Or under linux, read (if you are root) the
keyboard input file - I've done that to support several keyboards
attached to a machine.
And the original question: no, python can't be used as kernel
programming language. Amongst other reasons, performance & the GIL
prevent that.

Of course you can code kernel routines in Python -- you are just
calling the underlying C interface. The GIL means you have to manage
threadsafety on your own -- it doesn't imply kernel programming can
not be done.
I understood the OP's question as "can one program kernelspace routines
in python". Which I don't think is possible. And I don't see how py-pf
does that either.

OP: "I am wondering if python can do some kernel coding that

The answer is yes. IPC and py-pf are examples. If you don't think of
packet filtering as kernel coding, I can understand. But clearly the
Python interfaces to fork(), waitpid(), signal(), alarm() and so forth
are forays into the once private garden of C.
